Hi guy
i have a question to ask you, anybody can help me to reply?
In fact, i made a test playing now.
I made some video with the transparent background by After effect.
I want the ball that it can to pass before one video of head, it's not passed behind the video.

But i don't know why the ball passed behind the video, i tried to modify the order code, but,it's not good.
So,i hope you can help me by one idea ,it can pass before the video?
The other question is how can i import the video of sans transparence to processing?
Thank u.



//Define a variable of position
float x=30;
float xpos,ypos;
float xspeed= 3.0;
float yspeed= 2.0;

float xdirection= 1;
float ydirection= 1;

float radius= 15.0;


import processing.video.*;

Movie myMovie;
Movie myMovie1;
Movie myMovie2;
Movie myMovie3;

void setup() {
  size(640, 480, P2D);
  background(0);
  smooth();
  noStroke();
  // Load and play the video in a loop
  myMovie = new Movie(this, "2d.avi");//Load this video
  myMovie.loop();//Makes draw() run loop
  myMovie1 = new Movie(this, "Murdoc.avi");
  myMovie1.loop();
  myMovie2 = new Movie(this, "Noodle.avi");
  myMovie2.loop();
  myMovie3 = new Movie(this, "Russel.avi");
  myMovie3.loop();
}

void movieEvent(Movie myMovie) {
  myMovie.read();
}

void draw() {
 
  fill(0,12);
rect(random(xpos),random(ypos),width,height);
fill(0,0,255,50);
xpos = xpos + ( xspeed * xdirection );
ypos = ypos + ( yspeed * ydirection );

//x+=speed;
  if (xpos < 0 || xpos > width) {
    xdirection*=-1 ;
}
  if (ypos < 0 || ypos > height) {
    ydirection*=-1 ;
  }
 ellipse(xpos+x/4,ypos+x/4,x,x);
 
 // tint(255, 20);
 // image(myMovie, myMovie.width/2, myMovie.height/2);
//////// Displays the image at point (100, 0) at half of its size
image(myMovie, 0, 0,width/6,height/6);
